No doubt that the temporary wound channel causes damage to surrounding tissue and in some cases disruption to organs but "energy" is very very rarely fatal or even causes any wounds that would be considered potentially fatal. No doubt energy causes pumpkins to blow up and milk jugs to explode and surrounding tissue to bruise but if you read the original post, it isn't fatal....the hole is. The temporary wound channel, that release of energy if you will, may cause temporary disruption to the nervous system so you get that knockdown effect but without the hole, the effect would be temporary.

I'm not sure what you think you are seeing when a pumpkin blows up Axeman but in an animal, that temporary wound channel or as it's often called shockwave, rarely causes permanent damage.
